IMPROVEMENT IN MAGAZIbiE QUNS.

Specification forming'part of Letters Patent No. 213,565, dated April 1, 1879 application filed I I September 13, 1877:.

ment and combination of parts'hereinafter' more fully explained and described.

In the accompanying drawings, Figure 1 "represents-"a sectional si'clelevatioiVoftlie" a'rm. Fig.2 is a cross-section on the line an a; Fig. 3, a section of the forward part of the breech-bolt, showing the extractor and a m0dification of the ejector. Fig. 4 shows alink, and Fig. 6 a part of the lever detached. Fig. 5 is the lever as attached to the bolt by a single link.

Similar letters of reference indicate corresponding parts.

-The;receiver A contains a breech-bolt, B, which is operated back and forward by the links L and lever G. The carrier 0 is pivoted by the same pin that holds the hammer. The spring It tends to separate the carrier from the breech-bolt. The spring S straightens the joint 0 of the carrier. The spring '1. bears against shoulders on the guard-lever and the loadingtrap D, to hold both in position.

The roller'o'r wheel W forces down the carrier when it comes in contact with projection HI, and raises it by contact with projectionor shou'lde'r HQ. The sl v (De-F covers the opening in side when the receiver is not left open at the top.- The extractor E is pivoted to the breechbolt, andthe ejector .oimoves parallel to the -pits; r V

To-operate this armhe-guard-leveris'turned partly forward, and the cart-ridges are inserted into the magazine through the opening in the bottom of the receiver; is done by pressing the cartridge lag'ainstlthe trap D, and pressing it up against the-bottom of carrier enough to raise the end of carrier, (compressing the spring R,) and bending up the joint G of the carrier, so that the cartridge can be 1 forced forward into the magazine m. The trap D can be omitted, leaving the bottom of respring C -S can be dispensed with, and the operation remain essentially the same, the careach cartridge is inserted. The magazine be-' ward and opens the breech by drawing backv the bolt by the links L, The firing-pin presses over it. The roller W, havingpapsed along the curveC, comes in contact-withthe projection H, and forces down the carrier, which then receives acartridge from the magazine. Then "the leverG'lieihg tenet back the'roller' W and the breech-bolt drives the cartridge forward into the barrel, and the lower projecting cartridge and rotating on its pivot, causes the extractor-hook to fall over and hook onto the flange of the-cartridge, and thearm is tridge being exploded by a firing-pin through still more on the flange of the cartridge-shell by the force of the, shells resistance bearing on the pivot below contact of the-hook on flange at thesam'e timepressing against the when the ejector 0 comes in contact with the face of the hammer, which stops it suddenly, and the breech, with it's extractor-hook, still moving back, the shell is ejected from the arm through the side opening. This side opening has a cover, F,'wh-ich, being pivoted to the breech-block and links, by pin 1 moves open i of the breech-bolt,-bnt is alike applicable to the top or bottom of any arms having recipro- '.-cating breech-blocks. r 4

In practice, by leaving an openingon top of shown by dotted lines z 2, Fig. 1, the side opening and slide F are not used; but the carceivei' open, or either the spring R or joint and rier springing back to cover the opening as.

ing thus charged, the lever G is turned forback the hammer to full-cock and then rides i if raises the carrier by contact with point H,

point or points, e, reaching the head of the;

discharged bypulling the trigger, the car--' the breech-bolt. Then, by-again PPshingthe lever forward, the extractor-hook tightens the cartridge-flange, thef'opposite side of the end of stud 0" until the brcech is nearly back, 7

to allow the ejection, but closes with the breech. vIn this arm the'extractor is shown on the side receiverto eject the cartridge-shell from, as

fridges are fed in at the top when using the 2 erases arm as a single breech-loader, and all the .ihe ejector-,0 has a diagonal front that re- -mains forward of the face of the breech-bolt after having ejected a shell until another car- 1 eartridge, striking the face b, is in oy diagonal or glancing force forward pr. into thebarrel.

Having thus'f-deseribed .niy improvement, what Lelaim as new, and desire to s'egure by Letters Patent, is-

1-. A reeiprocatingbolt-tg close and open the Lreech,a link or links,-L, pivoted to said breecl'1-. bolt on a l ine withthe bore of the barrel, and in I combination therewith, the guard-leverpivoted to the other end of the link or links L, and operating to open, close, and lock the boltthrongh said lli1l-0011ll60l ion withoutintermediate part.

2. The continuous breech-bolt B, pivoted to and operated by the links L and lever G, all in combinatiomso that thejb'reech is locked against the'frame A, substantiall y as specified. 3, The'link or links L, pivoted directly to the reoiprocatingbolt, a gnard lever pivoted to the other end of said link or links, and op s thrown up by theearrier, so that the .erating therebyto moveand lock the breech, as described, in combination with thespring '1, for holding said lever and parts in position, substantially as specif ed. Y

- 4. Theibreech-bolt, links, and pin 1;, (30111 Joined to operate the slide F, substantially as described,

5. The pivoted" extractor having aprojee tion belowthe pivot or toward" the c'enter of breech-block that, closing against the head of a cartridge, turns the hook down over-the flan ge,'-substantially as set forth and described.- 6. A breeeh-bolt, or attachment thereto,

having-an inclined surface at the lower frontend, whereby a cartridge is given-a tendency to move forward when raised against the bolt, assetforth. i 7; A bolt, having orearrying an incline at its front end, in combination with a vibrating carrier, substantially as specified.

fly 8. A vibrating cartridge-carrier pivoted at *its rear'andextending forward -through or by the'operating-lever, a spring to press the front ofthe-earrier downward to stop the delivery end otltfhe magazine when the breech .is closed,

a projeetion, W, on the guard-lever to operate the carrier, and a curved surface, 0", eccentric withthe movement of the l ver, all-in' combination, to operate substantially as specified.
